Optimal Quantification of Functional Mitral Regurgitation: Comparison of Volumetric and Proximal Isovelocity Surface Area Methods to Predict Outcome

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Effective orifice area (EOA) ≥0.2 cm2 or regurgitant volume (Rvol) ≥30 mL predicts prognostic significance in functional mitral regurgitation (FMR).

Potential Efficacy of Multipoint Pacing in the Reduction of Mitral Regurgitation Volume: A Case Report

ESC Heart Failure, 2022
Abstract A 70-year-old woman who had cardiac sarcoidosis and severe tethering mitral regurgitation (MR) and had been implanted with a biventricular pacemaker experienced recurrent hospitalisation due to decompensated heart failure (HF).

Impact of bileaflet mitral valve prolapse on quantification of mitral regurgitation with cardiac magnetic resonance: a single-center study

Journal of Cardiovascular Magnetic Resonance, 2017
Background To quantify mitral regurgitation (MR) with CMR, the regurgitant volume can be calculated as the difference between the left ventricular (LV) stroke volume (SV) measured with the Simpson’s method and the reference SV, i.e. the right ventricular

Mitral prolapsing volume is associated with increased cardiac dimensions in patients with mitral annular disjunction [PDF]

, 2021
Introduction In patients with mitral annular disjunction (MAD), it can be difficult to assess the severity of mitral regurgitation (MR), as they present with a prolapsing volume (i.e.

Motion correction for the quantification of mitral regurgitation using the control volume method [PDF]

Magnetic Resonance in Medicine, 2000
Quantifying mitral regurgitation is difficult because of the complexity of the flow, geometry and motion of the mitral valve. In this paper a MRI compatible phantom was built incorporating a left ventricle and mitral valve motion. Valve motion was obtained using a pneumatic piston.

Quantification of regurgitation in mitral valve prolapse with four-dimensional flow cardiovascular magnetic resonance

Journal of Cardiovascular Magnetic Resonance, 2021
Background Four-dimensional cardiovascular magnetic resonance (CMR) flow assessment (4D flow) allows to derive volumetric quantitative parameters in mitral regurgitation (MR) using retrospective valve tracking.

Time variation of mitral regurgitant flow in patients with dilated cardiomyopathy.

, 1986
Angiographic results in patients with mitral regurgitation suggest that up to 50% of the regurgitant volume occurs during the preejection period. This contrasts markedly with the electromagnetic measurements of mitral regurgitant flow in anesthetized ...

Probe for production and measurement of acute mitral regurgitant flow in dog

, 1976
A probe for production and measurement of acute mitral regurgitation in dogs is described. It consists of a tube that is introduced into the mitral valve through the left atrial appendage.
